Physically trapping pathogens

Mucus is a slippery secretion produced by and covers the mucus membranes. It is produced by the goblet cells in the mucus glands. This secretions acts as protection of the epithelial cells. It is usually found in the digestive and respiratory tracts. This aids in trapping foreign particles particularly in the nasal area and some part of the repiratory tract. An increased production of mucus signifies that there is an abnormality in the secretions or there is an infection that is beginning.
